How reliable are these tests?

• These genetic tests are not completely reliable.

• Tests for detecting Cystic Fibrosis (CF) are only around 90% accurate.

• We do not yet have a cure for many inherited diseases, such as; Huntington's disorder, Cystic Fibrosis, Alzheimer's disease and Parkinson's disease.

• Only in a few cases will a genetic test not detect one of these inherited conditions, these are called False negative and False positive test results.

• False negative are tests results, that tell a person that they do not have a particular disorder when actually they do.

• False positive are tests results that tell a person they have a genetic disorder when really they don't. This type of test result is not a common as the other result.
